Description

The present invention relates to a general technical field of pressure cooking utensils for foods, and in particular, pressure cooking aimed at forming a cooking chamber in which pressure rises and reliably steam-pressing the food contained therein. Regarding vessel-type household utensils.

In more detail, the present invention
A bowl and a lid that is locked against the bowl and is intended to form a cooking chamber with the bowl that is adapted to pressure rise.
A bayonet-type locking system configured to reliably lock and unlock the lid with respect to the bowl by swiveling the lid with respect to the bowl.
A support intended to be attached to the lid so that the lid can rotate relative to the two positions corresponding to the unlocked configuration and the locked configuration, respectively, about the first axis of rotation.

With a converter, including at least one driven structure intended to be engaged by the drive structure.
It relates to a food pressure cooking utensil provided with a pressure adjusting means for maintaining the pressure in the cooking chamber at a set value level.

In particular, household food pressure cookware is well known. Generally, the purpose is to form a cooking room on which the pressure can be increased by firmly attaching the metal lid on the metal bowl using a flexible annular seal gasket.

The lid is connected to the bowl via a locking means so that when the lid is locked to the bowl, the pressure in the kitchen rises and when unlocked, the lid is free to disengage from the bowl. It has become.

In the prior art, various types of locking means are known. One of the most widespread systems is the bayonet lock system. It implements a gradient on the bowl and lid to ensure a mechanical retention link that slides into contact with each other after the lid rotates and prevents the bowl and lid from separating due to the effects of increased pressure. I am aiming.

The slope of the lid has traditionally been made by locally bending the annular falling edge of the lid inward, but the slope of the bowl is obtained by bending and cutting the free upper edge of the bowl.

Such bayonet locking systems are particularly satisfactory due to their relatively light weight, ease of manufacture and high reliability.

However, its most basic embodiment has some significant drawbacks, especially in terms of practicality and ergonomics.

To solve these problems, the bayonet pressure cooker is equipped with a force reduction control mechanism based on the implementation of a rotation control arch that drives the sliding movement of the carriage, and a rod that enables the rotation drive of the lid accordingly. It has been proposed to activate the system.

Such a system is also fully satisfactory in terms of ease of use and ergonomics. However, there are some drawbacks.

In particular, the maintenance and cleaning of this known pressure cooker can turn out to be complicated and cumbersome, especially considering the large number of parts attached to the lid, especially moving parts. Therefore, it is complicated, if not impossible, to wash this known pressure cooker in the dishwasher. Many parts attached to the lid directly or indirectly guarantee safety function. Therefore, repeated heat and mechanical stress can cause deterioration and damage over time and must be avoided. For this reason, it is prohibited to completely wash this known device in the dishwasher in order to maintain the above parts and mechanisms. Moreover, the bulk of the lid of this known pressure cooker, apart from other considerations, strongly limits or prohibits washing in the dishwasher.

Also, the bulk of this known pressure cooker lid complicates stocking and storage.

In addition, if one of the moving parts (rotating arches, slide carriages, rods, etc.) that form the force mitigation system implemented by this known pressure cooker is damaged or damaged, repairing it is a hassle even for specialists. It may take time.

Finally, most of the characteristic signs that belong to the commercial range of known pressure cookers described above are generally located in the parts attached to the lid. In fact, these parts can be shaped, colored, or surfaced so that the pressure cooker can be visually and clearly identified, simply and at a lower cost than the cover itself. Therefore, for pressure cookers of the same size, it is desirable from the viewpoint of industrial standardization to make the lid and bowl separately and differentiate them by the parts of the control mechanism attached to the lid.

Therefore, doing the industrial task of product differentiation as late as possible is of particular interest in order to maximize inventory flexibility and optimally adjust the production of such models according to market demands. That is.

However, the complexity of the control mechanism implemented by the known pressure cookers described herein arises from the implementation of multiple moving parts (rotary arches, slide carriages, rods, etc.) and in the production line by the lid. Known designs can prevent product differentiation at the end of the industrial process, as parts with different mechanisms to be transported need to be mounted relatively early. In addition to the inability to later differentiate products, the known pressure cooker designs described above also cannot benefit from a flexible and decentralized industrial organization.

Accordingly, an object assigned to the present invention is to improve the different shortcomings listed herein, to allow for particularly easy and flexible manufacturing, while being particularly easy and inexpensive to design, cleaning and storage of utensils, as well as. It is to propose a new food pressure cookware with a design that simplifies the possible repairs and makes it easily upgradeable.

As shown in the figure, the present invention relates to a food pressure cooker 1 for the purpose of reliably cooking various foods at a pressure level higher than atmospheric pressure in the presence of steam, for example, steam. be. Steam is generated by heating a cooking liquid, such as an aqueous liquid, in the utensil 1 in the presence of food. Although the device 1 according to the invention is preferentially intended for home use, it is understood that the invention may also relate to professional or semi-professional devices. The appliance 1 according to the present invention is designed so that the pressure is increased solely by the effect of a heating source (built-in or external) without applying external pressure. Therefore, the food pressure cookware 1 is primarily intended to constitute a pressure cookware and be placed on a separate cooking plate to heat its contents. The cookware 1 according to the invention includes at least a bowl 2 that forms a cooking container intended to receive the food to be cooked, the bowl 2 when the utensil 1 is in normal operation, i.e., on a horizontal plane. It has substantially rotational symmetry with respect to the vertical center axis XX'extending along a direction likened to the vertical when placed. The bowl 2 is still made of a metal material such as stainless steel or aluminum. The bowl 2 is composed of, for example, a bottom portion 2A which is a bottom portion of a multilayer heat conductor. Further, the bowl 2 has an annular side wall 2B that rises between the bottom portion 2A and the free upper edge 2C, and the side wall is circular here and defines an opening for accessing the inside of the bowl 2. Is. The shape of the free upper edge 2C will be described in more detail below in relation to the locking means of the instrument 1. Advantageously, and as shown in the figure, the cookware 1 is composed of at least one bowl handle 2D attached to the bowl 2 in such a way that it projects outward from the bowl 2. In the illustrated embodiment, the bowl handle 2D is intended to extend radially outward of the bowl 2 and to be picked up by the user to handle the bowl 2 (eg, to lift and move). It is attached to the outer surface of the side wall 2B of the bowl 2 so as to form a grip. In the illustrated embodiment, the cookware 1 comprises two identical handles 2D, 2E attached radially to the side wall 2B of the bowl 2 with respect to the central axis XX', and is a bowl handle. 2D and 2E are arranged near the free upper edge 2C of the bowl 2. However, the bowl 2 having only one bowl handle, or having two or more bowl handles (eg, three or four), thereby completely without departing from the framework of the invention. It is possible.

The utensil 1 according to the invention is also associated with the bowl 2 and is locked against the bowl 2 to provide a cooking chamber adapted to the pressure rise, i.e., a cooking chamber stiff enough to allow the pressure rise of the utensil 1. It consists of a lid 3 intended to be formed together. In order to obtain this hermetically sealed and rigid property, the appliance 1 is advantageously formed, for example, by a flexible annular gasket made of an elastomer, interposed between the lid 3 and the bowl 2 and with the interior of the kitchen. Includes a sealing gasket (not shown) intended to prevent uncontrolled leakage of steam and / or air to and from the outside. The lid 3 is made of a metal material such as stainless steel or aluminum as before. It advantageously has a shape conjugate to the shape of the bowl 2, eg, generally disc-shaped, and advantageously extends the bottom 2A of the bowl 2 when it is added to and locked into the bowl 2. It extends substantially parallel to the plane of existence (ie, in this case, substantially the horizontal plane). The lid 3 has an inner surface 30 intended to face the bowl 2 and an outer surface 31 on the opposite side thereof. In the illustrated embodiment, the lid 3 includes a disc-shaped covering element 3A of a shape and size conjugate to that of an access opening partitioned by the free upper edge 2C of the annular side wall 2B of the bowl 2. In this embodiment, the lid 3 also advantageously includes, for example, a substantially cylindrical or truncated annular band 3B. In the illustrated embodiment, the annular band 3B is formed by a falling edge extending downward from the peripheral edge of the disc-shaped covering element 3A. In this embodiment, the lid 3 is configured to substantially adjust and cover the upper part of the bowl 2 so that the annular band 3B surrounds the upper part of the annular side wall 2B and the free upper edge 2C from the outside. The disc-shaped covering element 3A is adapted to impose a load on the free upper edge 2C via a seal gasket (not shown) interposed between the bowl 2 and the lid 3. However, it is not intended that the annular band 3B is, as an alternative, inserted into the bowl 2 and thereby surrounded by the bowl 2 and contained within the bowl 2 without departing from the framework of the present invention. , Completely conceivable.

The food pressure cookware 1 according to the present invention preferably comprises a pressure regulating means 4 including, for example, a load or a spring-loaded valve for maintaining the pressure in the cooking chamber at a set point level, which is the user. May be adjustable (adjustable calibration valve). Advantageously, the pressure adjusting means 4 is configured by, for example, being conveyed by a lid 3, preferably attached to the lid 3. The pressure adjusting means 4 increases the pressure in the cooking chamber to a substantially constant predetermined value (set value level) called an operating pressure, for example, on the order of about 10 to 120 kPa, preferably 100 kPa, exceeding the atmospheric pressure by a certain threshold value. ) Is configured to maintain. The general operating principle of such pressure regulating means is well known by itself and does not need to be described in more detail herein. The food pressure cookware 1 can, of course, include other operating members (for example, an open safety means 5, an overpressure safety valve 6, etc., which will be described in detail below).

The appliance 1 according to the invention also allows the cooking chamber formed by the association between the lid 3 and the bowl 2 to reach at least the above working pressures without the risk of the lid 3 escaping under the influence of room pressure. Including a bayonet locking system in such a way as to. In other words, the locking system is designed to ensure a strong enough mechanical link between the bowl 2 and the lid 3 to prevent the lid 3 from separating from the bowl 2 under the influence of increased pressure in the cooking chamber. Has been done. More precisely, the bayonet locking system ensures locking and unlocking by swiveling the lid 3 with respect to the bowl 2 about the vertical center axis XX', after which the lid 3 is placed on the bowl 2. From the lock standby configuration (FIG. 1) freely resting on the bowl 2, the lock configuration (FIG. 10) in which the bowl 2 and the lid 3 interact with each other to prevent their free separation, and vice versa, the instrument 1 is It was designed to switch. Therefore, in the embodiment shown in the figure, the instrument 1 has a predetermined angular stroke (eg, 10 ° to 30 °, preferably 10 ° to 20 °, eg, 15 °) about the central axis XX'. By rotating the lid 3 in the first direction with respect to the bowl 2, the lock standby configuration is switched to the lock configuration. On the contrary, in the appliance 1, the lid 3 rotates with respect to the bowl 2 in a second direction opposite to the first direction along a predetermined angular stroke about the central axis XX'. , Switch from lock configuration to lock standby configuration. The bayonet-type locking system for the cookware 1 is advantageously integrated with the lid 3 (see FIGS. 5, 15 and 18) and the bowl 2 (see FIG. 2), respectively, to lock and unlock the lid 3 with respect to the bowl 2. To ensure, the first is designed to engage and separate from each other by rotation of the lid 3 with respect to the bowl 2 along a predetermined angular stroke about the vertical center axis XX'. It is composed of protrusions 7A to 7J and 8A to 8J of the first and second series. As is thus well known, the protrusions 7A-7J and 8A-8J of the first and second series are each intended to cooperate 2 to 2, i.e., one of the series. Each protrusion is adapted to lock the lid 3 relative to the bowl 2 by rotating the lid 3 relative to the bowl 2 and passing under the corresponding protrusions of the other series. In the illustrated embodiment, the first series of protrusions 7A-7J integrated with the lid 3 project radially toward the inside of the lid 3, while the second series of protrusions 8A-8J integrated with the bowl 2 project. Projects radially from the outer surface of the side wall 2B of the bowl 2 toward the outside of the bowl 2. However, it is completely conceivable that the lock projections 7A-7J of the lid 3 project outward of the lid 3 and then the projections 8A-8J of the bowl 2 radiate inward of the bowl 2. be. Therefore, the present invention is not limited to a specific configuration of the lock lamp (formed by protrusions 7A-7J, 8A-8J) of the bayonet system, and is essentially a lid lamp and a lid forming the bowl lamp, respectively. The protrusions 7A to 7J and the protrusions 8A to 8J of the bowl. By rotating the bowl 2 and the lid 3 relative to the vertical center axis XX', they cooperate with each other so that the lid lamp is under the bowl lamp, and between the bowl 2 and the lid 3 in the cooking chamber. Form a mechanical link that can withstand internal pressure. In the illustrated example, the protrusions 7A-7J of the lid are obtained by local volume deformation of the constituent material wrapping the lid 3, or more precisely, the annular band 3B in which the protrusions 7A-7J are preferably arranged at regular intervals. It is composed of the volume elements created. Thus, each protrusion forms an integral ridge with the annular zone 3B and projects from the annular zone, eg, by defining a convex inner surface on one side and an opposite concave outer surface on the other side. Corresponds to the application marks of forming tools, preferably drawing tools. However, the present invention is not absolutely limited to the implementation of the particular projections 7A-7J, and is particularly obtained by drawing, as in the example shown in the figure. For example, it is entirely conceivable that the protrusions 7A-7J of the lid are formed by flat tabs obtained by local folding back inward of the free end of the annular band 3B of the lid 3. In the illustrated example, the protrusions 8A-8J of the bowl are formed by an annular edge protruding outward from the free upper edge 2C, and the recesses 9A-9J are annular so that the protrusions 7A-7J of the lid allow passage. The portion of the annular edge formed through the edges and extending between the recesses 9A-9J is adapted to form each bowl lamp intended to cooperate with the lid projections 7A-7J forming the lid lamp. Therefore, when the lid 3 covers the bowl 2, the protrusions 7A to 7J of the lid can pass through the recesses 9A to 9J and reach a position lower than the annular edge. Next, the appliance 1 is in a pre-lock configuration (also called a lock standby configuration), from which the lock configuration can be reached simply by rotating the lid 5 with respect to the bowl 2 about the vertical axis XX'. It can, it is the effect of angularly offsetting the protrusions 7A-7J of the lid 3 and the recesses 9A-9J of the annular edge, providing a "bayonet" type lock.

According to the present invention, the appliance 1 also comprises a support 10 intended to be attached to the lid 3 in a removable (FIG. 1-12) or permanent (FIG. 13-18) manner, the lid 3 comprising: Between the two positions corresponding to the unlock configuration and the lock configuration, the first axis of rotation YY'(merges with the vertical center axis XX' when the lid 3 is placed on the bowl 2). It is configured to be able to rotate with respect to the support 10 around the center. The swivel link between the lid 3 and the support 10 can be made by any known means. The two positions in which the lid 3 can rotate with respect to the support 10 are, for example, from the pre-lock configuration (lock standby configuration) shown in FIG. 1 to the lock configuration shown in FIGS. 10 and 13. It is separated by a predetermined angular stroke that corresponds to what is needed to switch to.

Preferably, the appliance 1 comprises a lid subset 300 that includes both the lid 3 and at least the support 10 in an unlocked configuration (ie, the lid 3 is in a position corresponding to the unlocked configuration with respect to the support 10. ), And the bowl 2 are designed to be combined according to at least one predetermined relative arrangement corresponding to the pre-locking configuration of the appliance 1, and a bayonet locking system unlocks the lid subset 300. The lid 3 can be swiveled around the first rotation axis YY'and locked in the bowl so as to switch from the lock configuration to the lock configuration. In other words, by combining the lid subset 300 of the unlocked configuration and the bowl 2 according to the predetermined relative arrangement (pre-lock arrangement) shown in FIG. 1, interlocking occurs between the support 10 and the bowl 2. This prevents the support 10 from rotating about the vertical center axis XX'while resting on the bowl 2. By locking the relative angular positions of the support 10 and the bowl 2, the support 10 acts as a stationary frame with respect to the bowl 2, with respect to which the lid 3 is centered on the vertical center axis XX'. In addition, the bowl can be turned along a predetermined angular stroke, and the unlocked state (shown in FIG. 1) can be switched to the locked state (shown in FIGS. 10 and 13).

Advantageously, the support 10 and bowl 2 are preferably fitted together so that the lid subset 300 and bowl 2 in the unlocked configuration cooperate with each other when combined according to a predetermined relative arrangement (FIG. 1). It comprises complementary support structures 12, 13 and bowl structures 14, 15, respectively, intended as such. The fitting of the complementary support structures 12, 13 and the bowl structures 14, 15 locks the relative angular positions of the support 10 and the bowl 2 in the horizontal plane, i.e., in the plane perpendicular to the vertical center axis XX'. Make it possible.

In the illustrated embodiment, the bowl 2 comprises two bowl structures 14, 15 arranged radially opposed to the vertical central axis XX'. These two bowl structures 14, 15 are advantageously formed, for example, by parts having a substantially C-shaped profile, as seen in the figure. The C-shaped parts are, for example, conveyed by, for example, bowl handles 2D, 2E, and / or belong to these bowl handles 2D, 2E, respectively. Advantageously, the support 10 includes two support structures 12, 13 in their respective shapes complementary to the shapes of the bowl structures 14, 15. The two support structures 12 and 13 are advantageously arranged so as to radially face each other on the lid 3 with respect to the first rotation axis YY', and the support structures 12 and 13 are advantageous. Projects radially from the lid 3 and cooperates with the complementary bowl structures 14, 15. However, without departing from the framework of the present invention, the support 10 and the bowl 2 each have a single support structure and a single bowl structure, respectively, or the support 10 and the bowl 2 fit together. Support with interlocking elements of different nature based on the implementation of different types of cooperation (friction, clip, magnetic attraction, etc.) instead of the respective support and bowl structures intended to cooperate by fitting. It is even entirely conceivable that the relative angular positions of body 10 and bowl 2 are locked. Advantageously, the bowl structures 14, 15 form a female element, while the support structures 12, 13 form a male element complementary to the female element, the male element advantageously. Is intended to be inserted into the female element to establish a link between the support 10 and the bowl 2 that blocks rotation about the vertical center axis XX'.

Advantageously, the support 10 is preferably on the lid 3 (connected to the lid 3 by a swivel link), preferably a crossbar 100 extending longitudinally between two opposing ends that are free ends. Consists of. The crossbar 100 is advantageously formed by a substantially elongated portion extending radially on the lid 3. The opposing ends of the crossbar 100 forming the support 10 project radially from the lid 3 so as to cooperate with the complementary accommodating portions forming the bowl structures 14, 15 respectively, as shown in the figure. The constructed support structures 12 and 13 are formed. For example, the crossbar 100 has fins (FIGS. 1 to 12) at its free end, which form support structures 12, 13 that complement the accommodating portions 14, 15 partitioned by C-shaped parts integrated with the bowl 2. It is a form of an integrated rigid metal band forming an embodiment) or a falling edge (embodiment of FIGS. 13 to 18).

Thus, the lid subset 300 forms a kitchen in association with the bowl subset 400 (formed by the bowl 2 itself and at least the bowl handles 2D, 2E, and the bowl structures 14, 15 favorably carried by the latter of these). Form an independent single element intended for. In other words, when the lid subset 300 is in the unlocked configuration, the lid lamps 7A-7J are displaced by the docking of the support 10 to the bowl 2 at a predetermined position corresponding to the predetermined relative arrangement, and the recesses 9A, 9J separating the bowl lamps. The lid 3 and the support 10 are relative to each other so that they can pass under the bowl lamps 8A-8J via the lid, after which the lid subset 300 will cover the bowl 2 in a standby position. Then, the lid 3 may be swiveled relative to the bowl 2 from this standby position, and the lid 3 may be locked relative to the bowl 2. In other words, the bowl 2 and the lid subset 300 in an unlocked configuration combined according to the predetermined relative pre-locking arrangement illustrated in FIG. 1 once hold the support 10 in position with respect to the bowl 2 and the lid lamps 7A-. The 7J may be associated with the bowl lamps 8A-8J, the lid 3 may be swiveled relative to the support 10 and the lid 3 locked relative to the bowl 2 under these bowl lamps 8A-8J.

According to the present invention, the cooking utensil 1 includes a lock / unlock control member 11 that can be manually operated, that is, by manual operation of the control member 11, the unlock configuration is changed to the lock configuration, and vice versa. It is configured to be handled directly by the user so that the bayonet locking system can be controlled so that it can be switched in an advantageous manner. Therefore, the control member 11 advantageously makes it possible to control the switch from the pre-lock configuration (FIG. 1) to the lock configuration (FIGS. 10 and 13) of the appliance 1 and vice versa. The control member 11 is advantageously movably attached to the support 10 between a first position and a second position corresponding to unlocking and locking the lid 3 with respect to the bowl 2. .. More precisely, the control member 11 supports between the first and second positions corresponding to the unlocking (FIG. 1) and locking (FIGS. 10 and 13) of the lid 3 with respect to the bowl 2, respectively. It is intended to be permanently (as shown in the figure) or removablely attached to the support 10 by a mechanical link that allows manual movement of the control member 11 with respect to the body 10. In other words, the control member 11 is advantageous so that the user can manually move the control member 11 from the first position to the second position with respect to the support 10 and vice versa. Detachable or permanently attached to the support 10 while maintaining mobility with respect to 10.

The instrument 1 according to the invention further includes a device for converting the manual movement of the control member 11 into the swivel of the lid 3 with respect to the support 10. That is, the control member 11 is connected to the lid 3 by a conversion device. Therefore, the user controls switching from the unlock configuration to the lock configuration and vice versa by manual movement of the control member 11 relative to its first and second positions relative to the support 10. It is possible to do. Therefore, the conversion device is configured to convert the movement of the control member 11 with respect to the support 10 into the rotational movement of the lid 3 with respect to the same support 10, here the rotational movement with respect to the first axis YY'. When the lid 3 is placed on the bowl 2 having the lid lamps 7A-7J under the bowl lamps 8A-8J, the user can easily handle the control member 11 by turning the lid 3 with respect to the support 10. It allows lock / unlock to be controlled in that way. The control member 11 is in its first position and first position thanks to the interaction between the support 10 and the bowl 2 that is favored by the cooperation between the support structures 12, 13 and the bowl structures 14, 15. When moving between positions 2 and vice versa, the support 10 is prevented from turning relative to bowl 2 here about the vertical center axis XX'.

As shown in the figure, the converter is connected to the lid 3 and engaged by the drive structures 18, 19 with at least one drive structure 18, 19 intended to be conveyed by the manual control member 11. It is composed of at least one intended driven structure 16, 17. According to the first embodiment of FIGS. 1-12, the converter is, on the one hand, two driven structures 16 and 17 mounted on the lid 3 and disposed apart from each other, and on the other hand, preferably control. It is composed of two drive structures 18 and 19 which are separated from each other at different positions of the member 11 and are conveyed by the control member 11. In the second embodiment of FIGS. 13-18, the converter is composed of a single drive structure 18 that engages with a single driven structure 16. Of course, the present invention is not limited to a specific number of driven structures and driven structures, and a specific shape of the driven structure and driven structure.

In a first embodiment corresponding to FIGS. 1-12, the appliance 1 comprises a detachable link device 42 that ensures a detachable mechanical link between the control member and the drive structures 18, 19. It provides the possibility of relative movement between the control member 11 and the respective drive structures 18, 19 carried by the latter in certain anomalous situations. Hereinafter, the detachable link device 42 will be described in more detail. According to the alternative embodiments corresponding to FIGS. 13-18, each drive structure 18 is integrated with the control member 11 and there is no possibility of relative movement between the control member 11 and the drive structure 18 for control. It forms the same single integral part with the member 11.

Advantageously, one of the driven structures 16, 17 and the driven structures 18, 19 forms a female structure, while the other of the driven structures 16, 17 and the driven structures 18, 19 is female. Form a male structure intended to be accepted inside the mold structure. Advantageously, each male structure is substantially parallel to the first axis of rotation YY'in the female structure in which it is received, i.e., preferably along the vertical slide direction. It is slidable. In this preferred embodiment, each female structure is, for example, a hollow or rectangular hollow form that allows longitudinal guidance of the male structure inserted therein, while the male structure is Allows you to swivel on itself. Such an arrangement is extremely simple and highly reliable, and it is possible to mount a control member 11 that is rotatably attached around a second axis different from the first rotation axis YY'.

As in the example of FIGS. 1 to 12, when the conversion device is composed of a plurality of driven structures 16 and 17 intended to cooperate with the plurality of conjugated drive structures 18 and 19, the plurality of driven structures 16 , 17 and one of the plurality of driven structures 16, 17 forms a plurality of female type structures, and the other of the plurality of driven structures 16, 17 and the plurality of driven structures 18, 19 is a female type. Form multiple male structures, each intended to be accepted within the structure. In the example shown in the figure, each male structure is formed by driven structures 18 and 19, while each complementary female structure that internally accepts the male structure is formed by driven structures 16 and 17. However, the reverse configuration is fully conceivable as long as it does not deviate from the gist of the present invention. Advantageously, the cooperation between the driven structures 18, 19 and the corresponding driven structures 16, 17 has reversible properties, i.e., the driven structures 16, 17 and the driven structures 18, 19 are. , Advantageously coupled to each other, for example, the coupling can be disengaged under the action of the user on the instrument 1. When the driven structures 16, 17 and the driven structures 18, 19 are coupled to each other, that is, when each driven structure 16, 17 is engaged by the corresponding drive structure 18, 19, the action of manual operation by the user. Below, a drive mechanism capable of applying a rotational force to the lid 31 according to the movement of the control member 11 is formed. In the illustrated example, the driven structures 18 and 19 are advantageously formed by studs, while the driven structures 16 and 17 are formed by conjugated cavities that receive the corresponding studs. However, the invention is not entirely limited to this particular example, as an alternative, for example, the drive structure is formed by gears and each driven structure is formed by a rack that cooperates with the gears. That is completely conceivable.

According to the preferred embodiment shown in the figure, the control member 11 is advantageously mounted rotatably with respect to the support 10 about a second rotation axis ZZ'. Preferably, to support control ergonomics, the second axis of rotation ZZ'is parallel to the direction intersecting the first axis of rotation YY', as shown in the figure. Preferably, it is perpendicular to the first axis of rotation ZZ'. Advantageously, the control member 11 is, on the one hand, an extension position (first position) corresponding to the unlocked configuration, with the control member 11 projecting vertically, here outward, directly above the lid 3. Allows swiveling with respect to the support 10 between a position and, on the other hand, a storage position (second position) corresponding to the lock configuration, where the control member 11 moves downward toward the lid 3. It will be installed. Preferably, at its extension position, the control member 11 extends along an average direction substantially parallel to the vertical center axis XX'(as well as to the first axis YY'). On the other hand, in the stowed position, it advantageously extends along an average direction substantially perpendicular to the vertical center axis XX', as shown in the figure. In this preferred embodiment, the control member 11 therefore has a retractable property that allows it to be pushed aside when in its retracted position.

Advantageously, and as shown in the figure, the control member 11 consists of a handle 11A, which is therefore in the form of an arched portion having a loop or arch shape, which the user can grip firmly. As possible, it is preferably composed of a full hand or at least between the thumb and some fingers. Of course, the present invention is not limited to the implementation of handles for forming the control member 11, and the control member 11 may, for example, be configured with a substantially linear lever as an alternative. It is also possible to have a T-shaped, L-shaped profile, patterned or flared knob shape and the like. The handle 11A extends between the two ends 110, 111 passed by the second axis of rotation ZZ'. In other words, the handle 11A advantageously has a substantially U-shape or C-shape and is articulated to the support 10 at the ends 110, 111.

Preferably, at least one drive structure 18, 19 is carried by one of the ends 110, 111.

Therefore, in the embodiment of FIGS. 1 to 12, both end portions 110 and 111 carry the drive structures 18 and 19, respectively. For example, each end 110, 111 of the handle 11A advantageously cooperates with the respective bearings 21A, 21B for rotational mounting of the handle 11A about a second rotation axis ZZ', eg, respectively. Each ear portion 110A and 111A carrying the pins 110B and 111B of the above is formed. The bearings 21A, 21B are themselves advantageously attached to the support 10 by any suitable means (such as screwing). As shown in the figure, the selvages 110A, 111A are advantageously located towards the inside of the handle, with an inner surface facing the inner surface of the other selvage and corresponding pins 110B, 111B from there. Has an outer surface on the opposite side that extends outward coaxially with the second rotation axis ZZ'. In the embodiments of FIGS. 1 to 12, the drive structures 18 and 19 are rotatably mounted on the corresponding selvages 110A and 111A about the second axis ZZ', respectively. , Is carried by 19A. The rotatability for the selvages 110a, 111A, which support the intermediate parts 18A, 19A, is advantageously suppressed by the lock. The latter is accommodated, for example, by a cavity 22 formed on the surface of each intermediate component 18A, 19A to form a striker, and a cavity formed in each arm of the handle 11A by a cavity opened by the selvages 110A, 111A, respectively. It is formed by the corresponding bolts 23 and 24 elastically slidably mounted in the portions 23A and 24A. This reversible lock advantageously belongs to the detachable link device 42 described above. Below, we will enable the detachment function to be disclosed in more detail.

As an alternative, according to embodiments of FIGS. 13-18, the drive structure 18 (only) is carried by the end 111 and by projecting inwardly integrated with the inner surface of the handle 11A carrying it. Has been done.

According to the present invention, the instrument 1 includes a control module 200 that is detachably attached to the lid 3. As the name implies, the control module 200 supports at least one or several means for instructing or controlling the operation of the appliance 1. Preferably, the control module 200 supports the support 10.

The control module 200 is detachably attached to the lid 3 by any known means, for example by elastic fitting, screwing (as in the example shown), or any other mechanical fastening means. Can be done. For example, the appliance 1 advantageously comprises an assembly rod 27 that is borne by the control module 200 and projects from the control module 200, the appliance 1 is also formed through the lid 3 with the rod 27 being at least its free end. When screwed towards, for example, in cooperation with the nut 32, there is a central fastening hole 29 through which the rod 27 is allowed to attach the control module 200 to the lid 3.

More precisely, the control module 200 is responsible for at least one first subset 200A, which subset comprises at least the pressure regulating means 4 and the driven structures 16, 17. In other words, the control module 200 is in the form of a single set incorporating a first subset 200A, which itself is responsible for both the pressure regulating means 4 and at least one driven structure 16, 17. Thanks to the removable nature of the control module 200, it is possible to separate both the pressure regulating means 4 and at least one driven structure 16, 17 from the lid 3. This facilitates washing of the lid 3 which is a potentially fragile technical element and can be placed in a water wash or dishwasher without the risk of damaging the safe pressure regulating means 4. .. Further, the control module 200 is also responsible for at least one part of the converter, i.e., at least one part of the mechanism that allows the manual movement of the control member 11 to be converted into the swivel of the lid 3 with respect to the support 10. Thanks to this, when the control module 200 is removed from the lid 3, the user cannot control the lock / unlock. In fact, in this case, the manual movement of the control member 11 cannot be applied to the lid 3 as a drive torque. Thereby, in the absence of the control module 200, the risk of misuse of the appliance 1 can be limited. Similarly, thanks to the pressure adjusting means 4 being mounted on the control module 200, when the control module 200 is subsequently separated from the lid 3, the leak hole 38 does not communicate with the pressure adjusting means 4, so that the lid 3 Cannot form a dense cooking room with bowl 2. As a result, the safety of the instrument 1 can be ensured when the lid 3 does not have the control module 200.

Advantageously, the device for converting the manual movement of the control member 11 into the swivel of the lid 3 comprises a hub 25 intended to be attached to the lid 3 coaxially with the first axis of rotation YY'. The hub 25 carries at least one driven structure 16, 17 according to the illustrated embodiment. As shown, the hub 25 preferably forms at least one driven structure 16, 17 at its peripheral edge. Thus, each driven structure 16, 17 is advantageously supported by the hub 25 to form a single, same integrated portion with the hub 25. The hub 25 is provided with rotatability between the lid 3 and the hub 25 so that the force for rotationally driving the hub 25 around the first axis YY'is directly transmitted to the lid 3. It is preferred that it is intended to be attached directly or indirectly, rather than. Advantageously, the hub 25 forms a cap that serves to separate the containment for receiving the pressure regulating means 4. To that end, the hub 25 has, for example, a bell shape having an upper wall 25A and an annular side wall 25B, on its surface at least one extending vertically to form driven structures 16, 17 (FIG. 13 to 18) or two elongated cavities (FIGS. 1 to 12) are formed. The pressure regulating means 4 is advantageously located, at least in part, under the cap 25, i.e., under the upper wall 25A, thereby in the immediate vicinity of the center of the lid 3, i.e., the rotational stroke with respect to the support 10. Can be hidden while being placed in the position where is the minimum. This arrangement is advantageous, for example, for transplantation of complementary functional elements that facilitate cooperation with the pressure regulating means 4, and is therefore placed, for example, on the upper wall 25A. Advantageously, the appliance 1 also comprises a plate 26 intended to be placed on the lid 3 and under the hub 25, preferably with the hub 25 to form a containment for receiving the pressure regulating means 4. It is composed of. The plate 26 is advantageously attached to the hub 25 in a preferably permanent manner and preferably to the lid 3 in a removable manner and is a driven structure carried by the drive structures 18, 19 and the hub 25. It is intended to transmit to the lid 3 the rotational force about the first axis YY'applied to the hub 25 through collaboration with 16 and 17. Therefore, the pressure regulating means 4 is advantageously conveyed by the plate 26, with at least a portion covered by the hub 25.

Advantageously, the first subset 200A comprises a plate 26, which plate 26 is also supported by the control module 200. The plate 26 and the hub 25 therefore advantageously form an integrated casing in which the pressure regulating means 4 is located, the integrated casing also placing the control module 200 on the side wall 25B of the hub 25 and the control module 200 on the lid 3. When attached to the lid 3, they form one or several driven structures 16, 17 intended to be engaged by the drive structures 18, 19.

Advantageously, the appliance 1 comprises at least a control member 11, at least one drive structure 18, 19 as well as a second subset 200B including a support 10. The second subset 200B is advantageously intended to be rotatably attached to the first subset 200A about the first axis of rotation YY'. In the illustrated embodiment, the relative swivel of the first and second subsets 200A, 200B is controlled by manual operation of the control member 11 to cause the relative movement of the control member 11 with respect to the support 10.

In the first embodiment of FIGS. 1-12, the first and second subsets 200A, 200B are permanently attached to each other so as to advantageously form the control module 200.

According to the second embodiment corresponding to FIGS. 13 to 18, the first and second subsets 200A and 200B are detachably attached to each other.

The present invention relates to some scenarios, and particularly to the following scenarios.
-The control module 200 also has a second subset 200B in addition to the first subset 200A. This alternative is not intended that the first and second subsets 200A, 200B are removable from each other, as is the case with instrument 1 of FIGS. 1-12, but the first and second subsets 200A, 200B are not intended to be removable from each other. Subsets 200A, 200B of are permanently attached to each other, which can be the first sub-alternative. According to the second sub-alternative, since the first and second subsets 200A and 200B are detachably attached to each other, not only the control module 200 can be removed from the lid, but also the control module 200 is configured. The first and second subsets 200A and 200B themselves can also be separated from each other.
-The control module 200 has only a first subset 200A, which subset 200A is detachably attached to the second subset 200B and itself is attached to the lid 3 in a permanent manner, for example. .. In the alternative embodiment shown in FIGS. 13-18, the second subset 200 is permanently mobile to the lid 3 but relatively movable relative to the lid 3 (eg, dowels and slide systems not shown). The first subset 200A, which forms the control module 200, is detachably attached to the second subset 200B.

This latter embodiment is carried out herein using a control member 11 formed by a swivel handle between the ends of which the first subset 200A forming the control module 200 is located. Note that it is particularly advantageous. In fact, in this case, the module 200 is more difficult to separate from the second subset 200B when the handle 11A is extended (unlocked position) than when it is folded (locked position). be. Therefore, it is recommended that the user fold the handle 11A to separate the first subset 200A from the second subset 200B. In this way, the integrated subset formed by the association of the second subset 200B with the lid 3 is locked to prevent the user from rearranging the lid 3 on the bowl 2 in a functional position. This constitutes additional usage safety. In fact, in order to return the lid subset 300 to the unlocked configuration, the user first reattaches the control module 200 (here formed by the first subset 200A) and then lifts the handle 11A, thereby. A rotation of the hub 25 must occur and itself must be able to rotate the lid 3 from its locking configuration to its unlocking configuration so that the lid 3 can be positioned appropriately in the bowl 2.

In the first embodiment of FIGS. 1-12, preferably the crossbar 100 forming the support 10 is a subset formed by the crossbar 100 on the one hand and the plate 26 and the hub 25 on the other hand. It is arranged between the plate 26 and the hub 25 so that it can rotate relative to the rotation axis YY'of 1. It is preferable that the hub 25 is attached to the plate 26 by means such as screwing or elastic fitting, and the crossbar 100 is interposed between the hub 25 and the plate 26. In the second embodiment of FIGS. 13-18, on the contrary, the crossbar 100 is arranged under the plate 26 so as to be interposed between the lid 3 and the plate 26.

In either case (FIGS. 1-12 or 13-18), the hub 25 and the plate 26 therefore form the first subset 200A, while the control member 11 and the crossbar 100 form the second. The first and second subsets 200A, 200B form a subset 200B of, and the first and second subsets 200A, 200B are combined with each other so as to be relatively swivel about the first axis YY'. The pressure regulating means 4 belongs to the first subset 200A, preferably because it is supported by the plate 26. For example, the plate 26 is preferably in the form of a cup made of a plastic material and comprises a hole 26A intended to be arranged coaxially with a central hole 29 formed through the lid 3. The cup 26 advantageously has a lower surface 260 intended to face the outer surface 31 of the lid 3 and an opposite upper surface 261. A valve hole penetrating the cup is arranged between the lower surface 260 and the upper surface 261 of the latter. This hole is surrounded by a seal gasket 33 (not shown for alternatives of FIGS. 13-18) on the lower surface 260, on the side of the upper surface 261 itself, with a vertical hole 35 on the one hand and on the other hand. It is open to the chamber 34 that communicates with the exhaust pipe 36. The vertical hole 35 is a valve device with a weight or spring (FIGS. 13-18), for example, with a movable flap 37 slidably mounted along a direction parallel to the first axis of rotation YY'. Receiving (not visible in the alternative), the flap 37 is returned to a lower position (due to gravity or the effect of force exerted by an elastic body such as a spring). The flap 37 is formed through the holes arranged in the cup forming the plate 26 and through the lid 3 to close the leak hole 38 which is in close communication with the chamber 34 thanks to the seal gasket 33. Therefore, the flap 37 is sensitive to the pressure in the cooking chamber and alternately opens and closes the leak holes 38 to adjust the pressure level in the cooking chamber. When the pressure level in the chamber exceeds a predetermined working pressure, the flap 37 is lifted so that the steam contained in the cooking chamber first reaches the chamber 34 and then is discharged outward through the exhaust pipe 36. Will be done. Advantageously, the instrument 1 further comprises a device for calibrating the pressure regulating means 4, whereby the level of working pressure at which the valve 4 is triggered, i.e., the flap 37 is pushed out of its return position and a leak hole. The pressure threshold at which 38 is released can be adjusted. The calibrator may be of any known type (eg, acting on the compression of the return spring of the flap 37) and is advantageously coupled to the manual control device 39. The manual control device 39 is, for example, in the form of a tab that is rotatably mounted around a first axis of rotation YY'and extends between two ends, one of which is advantageously a pressure regulating means. Connected to the valve forming 4 to act on valve calibration, the other connected to a slide (alternative to FIGS. 1-12), a knob (alternative to FIGS. 13-18), or a manually operable lever. Has been done. According to the embodiment of FIGS. 1 to 12, the tab passes through the side wall 25B of the hub 25, for example, by passing through the slot 250 arranged through the side wall 25B. In embodiments of FIGS. 13-18, the tab remains beneath the upper wall 25A of the hub 25, which is provided with a slot 251 through which a control knob intended to be manually operated is passed. Of course, the use of pressure regulating means 4 with adjustable calibration is completely optional, and it is entirely conceivable to use a regulating valve whose calibration cannot be modified by the user.

Advantageously, the converter is supported by the first subset 200A and the lid 3, respectively, to allow rotational drive of the lid 3 around the first rotation axis YY'by the first subset 200A. Includes first and second complementary transmission members 43, 44 intended to cooperate with each other. That is, when the control module 200 is mounted on the lid 3 and attached to the lid 3 by the cooperation of the complementary transmission members 43 and 44, the control module 200 is placed around the first rotation axis YY'with respect to the lid 3. A subset 200A of 1 can be rotatably fixed. For example, the first transmission member 43 consists of studs that are integrated with the plate 26 (eg, one member with the plate 26) and are located away from the first rotation axis YY'. The stud 43 is advantageously formed by projecting towards the bottom of the bottom surface 260 of the plate 26 and penetrating the lid 3 and inserted into the corresponding plug hole 44 whose size is conjugated to that of the stud 43. It is intended. Therefore, the closing hole 44 forms a second transmission member. Thanks to the cooperation of the stud 43 and the plugging hole 44, the rotation about the first axis YY'applied to the first subset 200A and thus to the plate 26 via the hub 25 to which the latter is attached. The force is applied to the lid 3. An O-ring (not shown), or any other sealing system, is favorably placed on the stud 43 to prevent inadvertent communication between the inside and outside of the chamber through the closing hole 44.

Advantageously, the first subset 200A supports, for example, the assembly rod 27 protruding from the plate 26, preferably downward and coaxially with the first axis of rotation YY'. The assembly rod 27 is placed, for example, within the first subset 200A and the crossbar such that the second subset 200B swivels around the inner portion 27A about the first axis of rotation YY'. It has an internal portion 27A that passes through a hole 28 formed through 100. The rod 27 also preferably has a threaded free portion 27B that passes through a central fastening hole 29 formed through the lid 3, where the threaded free portion 27B is a nut 32 (FIGS. 13-18). The first subset 200A is attached to the lid 3 in collaboration with (not shown for alternatives).

In the first embodiment of FIGS. 1-12, the assembly rod 27 is used in this case to advantageously attach both the first and second subsets 200A, 200B forming the control module 200 to the lid 3. .. In this first embodiment, the assembly rod 27 advantageously comprises a flare head, while the hub 25 extends substantially coaxially with the first axis of rotation YY'and the support 10. A tube 25C that coaxially supports the outer surface 31 of the lid 3 with the hole 29 formed through the lid 3 through the hole 28 formed through the hole 28 and the hole 26A formed via the plate 26. Consists of. The rod 27 is advantageously screwed into the tube 25C, which has a constriction forming a shoulder intended to support the head of the rod 27. Therefore, the internal portion 27A is located on the side of the outer surface 31 of the lid 3, while the threaded free portion 27B passes through the central hole 29 formed through the lid 3 and cooperates with the nut 32. Is intended for. The O-ring 40, or other sealing system, is screwed into the rod 27 to ensure airtightness when the second subset 200A is attached to the lid 3.

In the second embodiment of FIGS. 13-18, the assembly rod 27 advantageously attaches the first subset 200A, which forms the control module 200 alone, to the lid 3 and the lid 3 by other means. It is used only for reversibly assembling to the present specification formed by a second subset 200B attached to the object. In this case, the rod 27 passes through, for example, a hole 28 formed through the crossbar 100 and is a first, between the first subset 200A and the second subset 200B centered on the rod 27. It passes through the first subset 200A in such a way as to allow relative rotation with respect to the axis YY'.

The first and second subsets 200A, 200B are advantageously assembled together, thus forming an integrated control module 200 detachably attached to the lid 3 by the assembly rod 27 and nut 32. ing.

Advantageously, the second subset 200B also includes a crown 41 forming an upper annular cap with a central hole 41A. In the first embodiment of FIGS. 1-12, the crown 41 advantageously covers the plate 26, the crossbar 100, the bearings 21A, 21B and the pins 110B, 111B, and causes the hub 25 to emerge from the hole 41A. .. In the second embodiment of FIGS. 13-18, the crown 41 reshapes the annular top cap that supports the handle 11A, which handle is supported by the crown 41 and rotatably attached to the crown 41. Be done. Here, the first subset 200A, including at least the hub 25 and the plate 26, is inserted into the central hole 41A formed by the crown 41 and the folded handle 11A. In this case, the driven structure 16 can advantageously slidably insert the stud forming the drive structure 18 into the groove when the first subset 200A is placed in the central hole 41A of the crown 41. As such, it is formed by a groove whose lower end is open.

Advantageously, the open safety means 5 is sensitive to pressure in the cooking chamber. Therefore, it is easy to move between different positions under the influence of the pressure level in the cooking chamber. In particular, the open safety means 5 blocks the lid 3 from unlocking when the pressure in the cooking chamber is substantially higher than atmospheric pressure, or at least higher than a predetermined pressure level higher than atmospheric pressure. It tends to occupy a position (see FIGS. 11 and 12). Advantageously, the open safety means 5 is at least partially permanently attached to, i.e., supported by the lid 3, thus forming a permanent portion of the lid subset 300. .. However, as an alternative, it is entirely conceivable that the open safety means 5 is supported by the first subset 200A or by the second subset 200B, thereby without departing from the framework of the present invention.

The open safety means 5 is intended to rotatably secure the lid 3 and the second subset 200B about the first axis YY'in the cutoff position in cooperation with the second subset 200B. is doing.

The open safety means 5 comprises, for example, a movable element 5A slidably attached to the lid 3, where the complement 10 is carried along a sliding direction parallel to the vertical center axis XX'. The blocking structure 5B (here, the hole) and the upper position (stop position) that can cooperate with each other are slid in the vertical direction. A position to prevent the lid 3 from turning to the support 10 and a lower position (return position and stop) that does not interfere with the complementary blocking structure 5B to allow the lid 3 to turn freely to the support 10. Position). As shown in the figure, the movable element 5A is advantageously formed by a finger portion intended to slide vertically in a tube 5C connected to a leak hole 5D formed through the lid 3. There is. In the upper position, the finger seals the leak hole 5D and in the lower position allows steam to leak from the hole 5D. The visualization window 41B is further arranged through the crown 41 so that the user can see it when the finger portion 5A is in the upper position, and the pressure level is so high that it is incompatible with the safe unlocking of the lid 3. Indicates the presence in the instrument 1. Unless a locking configuration is reached, the movable element 5A is not aligned with the hole 5B formed through the crossbar 100 and is therefore in its upper sealing position because it is approximately aligned with and below the crossbar 100. It is prevented from moving upwards to reach (see Figure 4). This prevents pressure rise in instrument 1 and constitutes safety against incomplete closure unless a locking configuration is reached.

Advantageously, the disengageable link device 42 (implemented in place of FIGS. 1 to 12) has the control member 10 from its second position (the storage position corresponding to the lock configuration) to its first position (implemented in place of FIGS. 1 to 12). The control member 10 and the drive structures 18 and 19 are configured to be disengaged from each other when the vehicle is moved to the extended position corresponding to the unlocked configuration. On the other hand, when the open safety means 5 is in the cutoff position, the control member 10 is free to move from the second position to the first position so that the drive structures 18 and 19 do not exert any driving force on the driven structures 16 and 17. Moving.

According to the embodiments shown in FIGS. 1 to 12, the disengageable link device 42 includes at least the following.
-It has each intermediate component 20 rotatably attached to one end of the handle 11A which is conveyed to the control member 11 and forms the control member 11.
-It is provided with bolts 23, 24 that are slidably guided by the accommodating portions 23A, 24A and are received in the corresponding cavity (striker) 22 formed on the surface of each intermediate component 20 to prevent its rotation.

The disengageable link device 42 is also arranged, for example, in the accommodating portions 23A and 24A that receive the bolts 23 and 24, and the bolts 23 and 24 are each of the intermediate parts 20 (FIG. 7). Includes an elastic return element (spiral spring or other not shown) that elastically returns to a locking position that engages the corresponding cavity 22 located on the surface of the (see) surface and prevents rotation of the intermediate component 20 with respect to the handle 11A. There is. When the opening safety means 5 is in the shutoff position and the user nevertheless exerts an unlocking force on the handle 11A with the aim of switching the handle 11A from the retracted position (folded to the lid) to the extended position. The finger portion 5A is inserted into the hole 5B of the crossbar 100, and the hub 25 cannot rotate. At this time, if the user continues to apply a force to the handle 11A, the driving force exerted by the user on the handle 11A overcomes the return force exerted on the bolts 23 and 24 by the return spring, and the bolts 23 and 24 have the corresponding cavities 22. As a result, the handle 11A can be turned with respect to each intermediate component 20 without moving. Therefore, the rotational movement of the handle 11A is not applied to the drive structures 18 and 19 so that the hub 25 does not receive the driving force. As a result, an inadvertent force is applied to the lock / unlock mechanism to prevent a part of the control mechanism from being damaged. The handle 11A is then located on the opposite side of the corresponding cavities 22 with the bolts 23, 24 and is again inserted into the corresponding cavities 22 under the influence of the return force exerted by the spring, resulting in the drive structure 18 , 19 In order to make a rotation drive link centered on the second axis ZZ', it can be reattached by the user simply by returning it to its storage position.

Advantageously, the second subset 200B has a disengageable link device 42. This makes it possible to maintain additional safety features permanently associated with the lid 3, for example, in embodiments of FIGS. 13-18 where the second subset 200B remains permanently attached to the lid 3. Will be.

Therefore, the device 1 according to the present invention has a high level of safety and reliability.
